COMPOSITION HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 779,757, dated January10, 1905.

Application filed January 5, 1904. Serial No. 187,784.

T0 on whom it may concern:

Be it known that I, HARVEY BARTLEY, a citi- Zen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inComposition Horseshoes, of which the following is a specification,reference being had therein to the accompanying drawings, forming a partof this specification, in which Figure 1 is a face view of the underside of my horseshoe, showing the cushioning substance removed fromone-half of the base. Fig. 2 is an edge view of the shoe. a back endview. Fig. 4 is a cross-section on the line IV IV of Fig. 1. Fig. 5 is apartial similar section showing a modified form of nail-abutment. Fig. 6is a partial face view of the base, similar to the exposed portion ofFig. 1, showing a modified arrangement of anchors at the front. Figs. 7and 8 are crosssections on the lines VII VII and VIII VIII of Figs. land6, respectively. Fig. 9 is a perspective detail view showing two' of thenailing-abutments.

My invention relates to improvements in combination horseshoes, in whicha cushioning portion is incorporated with a holdingbase; and it refersmore particularly to the construction of the base and to the supportingand securing devices for the cushioning portion, whereby these parts aresecurely incorporated with'each other; also to the reinforced nail-holeprojections, the retaining edges of the base, and to the various otherfeatures of construction, as more fully hereinafter set forth.

Referring now to the drawings, 2 is the base, made of one integral pieceof metal, preferably of forged or cast steel or aluminium. This metalportion is of substantially the full length and width of the finishedshoe, its main body portion comprising a thin plate-like base ofpractically uniform thickness, as indicated at 3, having at the frontend a reinforced toe 4, adapted to bear on the ground and at the rear,on each side, similar heel-reinforcements 5. The outer edge of the basemay be of the same thickness as its body portion or may be provided atone or both sides, but preferably Fig. 3 is at the under side only, witha projecting flange or lip 6. Extending backwardly from the toeExtending inwardly from the base are a series of holding anchors 9,terminating in downwardly-turned lipslO, concave recesses 11 beingprovided between adjacent anchors to facilitate the interengagement andholding embodiment of the cushioning substance with the shoe. As shownin Fig. 6, the series of such anchors is continuous around the inneredge of the base, and it will be seen that by this means suitableholding devices are provided at close intervals, with which thecushioning substance will closely engage and form a tightbond. Extendingdownwardly from the base, integral with it and suitably arranged as tolocation, are a series of nailing pipe-like abutments or projections 12,perforated clear through by suitable nail-holes 13.

These projections may be of the full depth of the shoe, as in Fig. 5, inwhich case they are countersunk for the head of the shoe-nail, as at 14,or of a less depth, as in Fig. 4, in which case the nail-head is simplyembedded in the cushion. In either construction the projections formpiers or supplemental anchors around which the cushioning substance isembedded and with which it will become firmly incorporated, therebygreatly increasing the strength of the holding connection between thebase and cushion.

For the purpose of providing additional holding-recesses the toe may beprovided at each end with cavities or recesses 15, as in Fig. 6, and itwill also be seen that the inner edge of the toe extends'around at eachside, as indicated at 16, thereby providing an additional holdingelement.

The cushioning substance, which is either of rubber or a combination ofrubber and canvas or of any other suitable combination or othermaterial, is indicated by the numeral 17 and is pressed into theholding-cavities and around the anchoring portions and abutments of theshoe-base, so as to completely fill such cavities and surround theholdingcavities, as clearly shown. The cushioning substance ispreferably forced around and over the entire upper portion of the base,thus providing a good bearing-surface for the hoof. In attaching theshoe the nails are driven through the openings 13 and the uppercushioning layer and into the hoof in the usual manner. v

By making the main body portion of the base thin and flat and inclosingit within the cushioning substance it will be seen that almost theentire wearing-surface of the shoe is composed of the rubber or othercushioning substance employed. This is of great advantage in offering africtional bearing for the hoof and in reducing the metalbearingsurfaces toaminimum. As thus constructed 1 have provided a veryserviceable and efficient horseshoe capable of long continued use and ofholding the cushioning substance I tightly to the base withoutdisplacement under the excessive wear or jar incident to devices of thiskind.

Changes and variations may be made by the skilled mechanic in thedesign, proportions, or other details of the inventionas, for instance,the number, location, and shape of the holding-anchors; but all suchchanges are to be considered as within the scope of the followingclaims.

What I claim is 1. A horseshoe-base provided on its inner sides withinwardly extending holding anchors having downwardly-turned lips andconcave recesses between said anchors, substantially as set forth.

2. A horseshoe-base provided on its under side with integral hollownailing-abutments projecting beyond the surrounding surface of the base,substantially as set forth.

3. A horseshoe-base provided on its under side with integral hollownailing-abutments projecting beyond the surrounding surface of the baseand having countersunk nail-head cavities, substantially as set forth.

4. A. horseshoe-base provided with a plurality of inwardly-extendingholding-anchors having downwardly-turned lips, intervening recesses, anda reinforced toe of thefull depth of the shoe having an underretaining-groove between its front and back portions, substantially asset forth.

5. A horseshoe-base provided with a plurality of inwardly-extendingholding-anchors having downwardly-turned lips, and a reinforced toe ofthe full depth of the shoe having an under retaining-groove between itsfront and back portions, and holding-recesses at its ends, substantiallyas set forth.

6. A composite horseshoe consisting of a base having inwardly-extendingholding-anchors provided with downwardly-turned lips, with concaverecesses between the anchors, and a cushioning substance incorporatedthere'- with, substantially as set forth.

7. A composite horseshoe consisting of a base having integraldownwardly-extending nail-hole abutments projecting beyond thesurrounding surface of the base, and a cushioning substance incorporatedtherewith, substantially as set forth.

8. A composite horseshoe consisting of a base having inwardly-extendingholding-anchors provided with downwardly-turned lips with concaverecesses between the anchors, and a reinforced toe with holding-recessestherein, and a cushioning substance incorporated therewith,substantially as set forth.

9. A horseshoe-base provided on its under side with integral isolatedhollow nailingabutments, substantially as set forth.

10. A composite horseshoe consisting of a base having integral isolateddownwardly-extending hollow nailing-abutments, and a cushioningsubstance incorporated therewith, substantially as set forth.

In testimony whereofI affiX my signature in presence of two witnesses.
